I had a problem with the State attribute. This is the attribute that is saved inside the span [SPAN class=dynamiccontent contentEditable=false style="....." disabled hash="oqAE..zt1Y=" state="xxx"][/SPAN]
I tried to save some xml inside it, and the dynamic content render just wouldnt save. it seems like the attribute can contains html/xml tags.
The trick was to convert my string into Base64.
public string Value;
#region Value64 public string Value64 { get { if (Value == null) return null; return Convert.ToBase64String(System.Text.Encoding.UTF8.GetBytes((string)Value)); } set { if (value != null) { byte[] toDecodeByte = Convert.FromBase64String(value); System.Text.UTF8Encoding encoder = new System.Text.UTF8Encoding(); System.Text.Decoder utf8Decode = encoder.GetDecoder(); int charCount = utf8Decode.GetCharCount(toDecodeByte, 0, toDecodeByte.Length); char[] decodedChar = new char[charCount]; utf8Decode.GetChars(toDecodeByte, 0, toDecodeByte.Length, decodedChar, 0); string result = new String(decodedChar); Value = result; } } } #endregion #region State (64) public string State { get { return Value64; } set { Value64 = value; } } #endregion
